Je reçois une erreur quand il essaie de créer le scanner pour les fichiers dans les fonctions de construction. Une fois le fichier créé, il possède le chemin d'accès au fichier, mais lorsque l'analyseur tente d'utiliser le fichier, il ne peut pas trouver le fichier en question. Il échoue pour les deux scanners. Je viens de commencer à travailler dessus il y a un petit moment, et avant cela, ça marchait bien, je n'ai pas modifié les méthodes de construction ou la section de balayage pour déboguer, donc je sais que c'est toujours la même chose. (La première méthode de construction a enlevé le code de débogagez). *** Je posterai une image si les gens veulent du fichier, assis là dans "C: \ Users \ User \ Documents \", je sais qu'on me demandera si le fichier est là.Java, Impossible de trouver le fichier texte, avec un StkTrc
